Strange water behavior...

'02 Winnebago Journey 36'

Water and plumbing tends to be a mystery to me and my RV has developed this water problem that leaves me scratching my head:

Turn the kitchen faucet on 'full' and the water starts out with a slightly lower then normal flow. After a few seconds, it's slowed to a trickle. Go back to the bathroom sink, turn it on full, and it's nearly full volume. And then the kitchen flow jumps up to nearly normal.

This only happens on shore water (and I have a 45 PSI pressure reducer at the shore water faucet). This park and all the others I've visited since this started happening a few weeks ago have had greater than 45 PSI.

I have one of those under sink filters in the kitchen but the bathroom faucet does something similar...when I turn it on full, is starts out full flow, but slowly reduces, so I don't think it's the filter.

No sputtering at all. Does the same thing with the single handled faucets set for full cold or hot, but seems more pronounced with the hot side.

Any ideas?

    Unscrew the filters from the ends of each faucet and you may find they are full of debris. The debris is not necessarily from particles in the water but can be from dried mineral deposits from the water through the years.

    Happens JUST at 'sink' faucets....aerators

    Happens at sink faucets/shower and toilet
    City water inlet screened washer clogged or city water inlet check valve malfunctioning

    Remove the Water Regulator from the system. Then see if the problem returns. Doug

    Just got all set up to do this and checked the water pressure. 104 PSI. So I guess it'll have to wait for when I'm at a park with a bit lower pressure.

    Sounds like it's the check valve where the water hose connects to the RV. This is a backflow valve. Remove the water hose and screen and see if the plunger works. I'm guessing when you open the second faucet, you release the pressure on the checkvalve....Dennis

    104 PSI?????? I would suspect your gauge and regulator is indeed malfunctioning. Doug

    I suspect that what's happening is that when you open the 2nd faucet there is enough demand for the water pumps to kick and you are getting full flow. The regulators are actually terrible at getting much of a flow rate and highly restrict your water flow. I keep my tanks full and use the pumps only as they provide the best water pressure. You can also get a better water pressure regulator that has better water pass through. There are several but they are a bit more expensive. These will have a dial where you can select the pressure output you prefer (and it does not have to be 45#) and get the flow you like.

    Apparently some people that travel a lot have found RV parks with very high water pressure. At my house, 80-90 psi is the norm.
    In any case, here are some of our fellow travelers that mention water pressures at 140 and 160 psi. I remember an RV park in Las Cruces, NM that had warning signs requiring a pressure regulator because of their high water pressure. 104 psi might indeed be possible. High water pressure
